I’m being slowly swayed towards being okay with calling it chromatography purely by the literal definition of chromatography being so vague. But in most context, people consider elution based on retention times a key facet of true chromatography. Otherwise they call it filtration if these things are not being measured or taken into account. Is all filtration chromatography in some sense? Are we sure that we aren’t performing particle size filtration here instead of creating a mobile and stationary phase that all of the components will eventually elute through given enough solvent and time? I think this is another point that needs discussed here.
But I think the point about the nomenclature difference between filtration and chromatography still stands, and I still see benefit in changing the nomenclature to more accurately match the actual goals of the process. Does it actually make more sense to call what most people are doing, filtration? (except for those very few that are actually eluting fractions based on retention times, in which case I agree this is absolutely chromatography and should be called so, and would specifically be called “preparatory scale column chromatography” in the lab world).
Sure it’s all semantics, but is there not some benefit in using more accurate nomenclature based on the desired effect of the process?
Precisely! I use a simple column of MagSil to “remediate” or “separate” pesticides and cannabinoids resulting in 2 “fractions” … pesticides and everything else. Same as color remediation results in 2 “fractions” … pigment and everything else. And same as THC remediation etc. etc.
Who calls it color remediation chromatography? That’s like saying THC remediation chromatography…which I guess makes it relatively accurate seeing as they both use a column of media and the same mechanism of separation…so if anything you’re validating the nomenclature in my eyes
That’s not 2 fractions. If you had 2 fractions you would have thc in w.e solvent used AND pesticides in w.e solvent used after pushing thru the magsil bed.
If thats chromatography than so is reverse osmosis systems, desolvation/membranes are as well. Separating one compound with a media that catches is not chromatography.
So plant material from the columns is caught by a screen/powder. It was separated so it must be chromatography right?
Molds mildew and anything that gets caught by over .2 micron is not filtration anymore guys its chromatography.
Shit I commit some ill raps and chromatography every day when I make my coffee too.
Look at the picture for its definition yall notice the separate fractions BEING ELUTED? Yall seem to miss that for it to be chromatography the remained fractions must be eluted from said column. Not filtered
